WideLine Engineering
WideLine systems follow the classic high performance hot rod formula:
engineer maximum horsepower into a package with minimum size and weight.
For transparent high frequencies, they use a compression driver with
a 3" (75 mm) diaphragm and neodymium magnet. For midrange punch and
low-frequency authority, a pair of high-performance 16 ohm woofers
– 8" (200 mm) cones in the WideLine-8 and 10" (250 mm) woofers in
the WideLine-10 are employed. For optimal overall amplifier efficiency,
in tri-amp mode the LF and MF sections of up to eight enclosures can
be powered by a single two-channel amplifier.

Coverage
WideLine systems have exceptionally wide 140° horizontal coverage.
They create a broader stereo image, reduce the need for supplemental
fill speakers and give you more placement options.

Two engineering achievements let WideLine
systems cover more seats with fewer boxes. Covering high frequencies
is QSC's patented multiple aperture diffraction slot waveguide. The
waveguide exit extends nearly to the top and bottom of the enclosure,
minimizing discontinuities between adjacent elements. This virtually
eliminates destructive interference and creates a flexible, continuous
acoustical source.
Both WideLine systems operate in 3-way mode. One woofer covers only
the low frequencies while the other extends to the mid/high crossover
point. The single midrange transducer keeps horizontal coverage as
wide as possible and assures smooth response both on and off axis
at the transition to the diffraction-slot-loaded high-frequency section.
Subwoofer Integration
Sound system designers and operators are increasingly flying subwoofers
with the main array for a more seamless acoustical transition from
low-mids to subbass. Both WideLine systems have arrayable subwoofer
options. |

Intrinsic Correction™
Phenomena such as waveguide acoustical impedances and loudspeaker
cone resonance gave every loudspeaker its own character – until
now. QSC system engineers have harnessed digital FIR (Finite Impulse
Response) filters to provide Intrinsic Correction of these
"unavoidable" acoustical errors. Intrinsic Correction provides
the most accurate acoustical magnitude, frequency and phase domain
performance possible, giving WideLine systems excellent power response
and extremely natural, uncolored sound. For flawless audio quality,
operational simplicity and low cost, the QSC SC28 processor combines
factory-programmed Intrinsic Correction tunings with user-adjustable
system equalization, offset delays and output levels. For sophisticated,
programmable DSP, Intrinsic Correction tunings are available
for QSC BASIS™ processors. Thanks to Intrinsic Correction,
WideLine arrays are totally responsive to any equalization you may
apply as an adjustment for array configuration, acoustical conditions
or individual preferences.
